IMPROVEMENT IN FURROW-GAGE STAFFS FOR DRESSING MILLSTONES.

' Specification'forming part of Letters Patent No. 209.373, dated October 29, 1878; application filed September 7, 1878.

an improved gage-staff, by which all the furrows may be quickly gaged and then cut exactly alike in Width and depth; and the invention consists of a staff with adjustable side strips or rests, the bottom of the staff being made in the shape of the furrow.

Referring to the drawings, A represents the staff of my improved device for gaging the furrows of millstones, and B and G are side strips or rests, which are made adjustable by means of slots a and clamp -screws 12 for a greater or less depth of furrow. The upper part of the staff A is concaved or indented at the sides, so as to be conveniently taken hold of, while the bottom A of the staff corresponds in shape to the shape of the furrow. The side rests, B and C, have longitudinal recesses d at the lower inside corners, to facilitate the painting of the bottom of the staff A' without getting any paint on the bottom of the rests B and 0, so that the burr shall not be painted outside of the furrows.

In order to suit the different widths of furrows used on different stones, the staffs will be made of different thicknesses.

The side rests are adjusted to the proper position at the sides of the staff to obtain the desired'depth of furrows.

The bottom of the staff is painted, and the gage device then passed over the furrows.

The uner'en spots are covered with paint, and are then picked down. This is repeated until the stafi' will paint no more, in which case all the furrows are alike, so that each performs its share of the work, grinds the meal even, with less specks, makes; cleaner bran, and furnishes a better grade of flour.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent A furrow-gage stalf consisting of a center stafl', whose bottom corresponds to the shape of the furrow, and of adjustable side strips or rests, substantially as and for the purpose specified.
